3CX Upgrade Insurance licences are annual contracts that provide for free software version upgrades and product patches during the course of the contract. All new 3CX Phone System Licences include a one year Upgrade Insurance licence. An existing Upgrade Insurance Licence can be extended if the new licence is purchased no later than 30 days after the expiry of the old Upgrade Insurance Licence (otherwise a complete new Upgrade Insurance licence will need to be purchased at higher cost).
